## Questions & Answers

**Q: How can I determine if this is the right product for my model?**
A: Because this Cranksets is square hole shaped, you will need a square tapered bottom bracket to go with it.Note that this crank is a 170mm size and the length of the crank is chosen according to personal habits.

**Q: How do I adjust the chain alignment? Is there a spacer I can put somewhere to help centre the chain?**
A: The chain ring mounting area has two sides. Placing them on either side will move the chain ring about 10mm. Do not use washers between the crank and the ring because there are no chain ring bolts that are long enough.

**Q: How do you orient the chainring on the crank arm?**
A: One the crank arm attaches to the chainring and then to the bottom bracket square taper bolt the other crank arm attaches to the bottom bracket square taper bolt on the other side one arm points up the othe points down direct opposite see less.

**Q: What is used to secure the arms to the square taper bottom bracket arms if no screws or caps are included?**
A: It depends on your application. A new bottom bracket will come with crank bolts. Or if replacing a existing crankset, you would just resuse the old crank bolts.

**Q: Does this product include crank/bottom bracket bolts and caps? If not included, which set should I order?**
A: Hello! The package of this product includes a left crank arm, right crank arm and a chainring with 4PC chainring bolt. Does not include bottom bracket or caps. I hope this answer is helpful to you.

    Light weight and sturdy.
  

*by C***N on Reviewed in the United States on 20 August 2021*

seems durable and lighter than my stock crank. Swapped to a 1x11 drive and ditched my old 2x8 with this crank. Love the torque from the 32t oval ring also.
